Factual error: As Walker and Atwood are falling from the building in 1929 New York City, the reflection of Vancouver's Harbor Centre is visible in windows. Furthermore, the Harbor Centre was completed in 1977, so this is a double goof. (00:22:45)
Fielding: I really could care less whether you like me or not, but you don't know a thing about me. I was with IA for two years, I'm field-rated in weapons and tactics, and speak three languages. Impressed?
Walker: I'm blown away.
Fielding: I read the Atwood file.
Walker: You didn't mention you could read.
Answer: I'm pretty sure it was mp5 with muzzle brake.
